Abstract

An ignition fluid, which is injected into the fuel-air mixture of a combustion engine, especially a gas engine, comprises dimethyl ether. A dimethyl ether storage tank (3) is preferably used to supply dimethyl ether via a pump (1) and a nozzle (4), directly into the main combustion chamber (5).

Description

Die Erfindung betrifft ein Zündfluid, welches zur Zündung des Kraftstoff-Luft-Gemisches in einen Ottomotor, insbesondere Gasottomotor, eingespritzt wird.The invention relates to an ignition fluid which is injected into a gasoline engine, in particular a gasoline engine, to ignite the fuel-air mixture.

Eine mit dem Hauptbrennraum kommunizierende Vorkammer mit elektrischer Zündung dient zur Verstärkung der Zündenergie bei Ottomotoren im allgemeinen und bei Gasottomotoren im speziellen. Vorkammern in Gasottomotoren werden ab einem bestimmten Zylinderdurchmesser allgemein eingesetzt. Vorteil ist das stabile Verbrennungsverhalten, Nachteil ist der teilweise extrem große Kerzenverschleiß aufgrund hoher Temperaturen.An antechamber communicating with the main combustion chamber with electrical ignition serves to amplify the ignition energy in gasoline engines in general and in gasoline engines in particular. Antechambers in gasoline engines are generally used from a certain cylinder diameter. The advantage is the stable combustion behavior, the disadvantage is the sometimes extremely large candle wear due to high temperatures.

Bei steigenden spezifischen Motorleistungen nehmen die erwähnten Nachteile der elektrischen Zündung in der Vorkammer zu. Eine alternative Lösung besteht in der Einspritzung einer kleinen Menge Diesel als Zündfluid (z.B. DE 44 04 899). Um die Entflammung zu gewährleisten, muß die Einspritzung in eine Vorkammer erfolgen, in der zusätzlich eine Glühkerze als Zündhilfe angebracht ist. Nachteilig ist hiebei die relativ schlechte Entflammbarkeit von Diesel in einem Gas-Luftgemisch sowie die Notwendigkeit einer Zündhilfe in Form einer Glühkerze.With increasing specific engine outputs, the disadvantages mentioned of the electric ignition in the prechamber increase. An alternative solution is to inject a small amount of diesel as the ignition fluid (e.g. DE 44 04 899). In order to ensure the ignition, the injection must take place in a prechamber, in which an additional glow plug is installed as an ignition aid. Disadvantages are the relatively poor flammability of diesel in a gas-air mixture and the need for an ignition aid in the form of a glow plug.

Die DE 44 19 429 A1 zeigt einen Motor mit Vorkammer, in die Hochdruckgas eingeblasen wird. Damit soll der Nachteil der Notwendigkeit von Diesel als Zündfluid vermieden werden. Man hat damit allerdings den weiteren Nachteil des sehr hohen Energiebedarfes für die Gasverdichtung und die noch schlechteren Selbstzündeigenschaften von Gas anstelle von Dieselkraftstoff zu tragen.DE 44 19 429 A1 shows an engine with a prechamber into which high-pressure gas is blown. This is to avoid the disadvantage of the need for diesel as an ignition fluid. However, this has the further disadvantage of the very high energy requirement for gas compression and the even poorer auto-ignition properties of gas instead of diesel fuel.

Aufgabe der Erfindung ist es, einen mittels eines Zündfluids gezündeten Ottomotor zu schaffen, der sich durch einfachen Aufbau und hohe Standfestigkeit auszeichnet.The object of the invention is to provide a gasoline engine which is ignited by means of an ignition fluid and which is distinguished by a simple structure and high stability.

Dies wird erfindungsgemäß dadurch erreicht, daß das Zündfluid Dimethylether (DME) enthält.This is achieved according to the invention in that the ignition fluid contains dimethyl ether (DME).

Kern der Erfindung ist also die Verwendung von Dimethylether (DME) als Zündfluid zur Zündung von Gasottomotoren. Hiebei kann sowohl eine Ausführung mit Einspritzung in eine Vorkammer gewählt werden, hier allerdings ohne die Notwendigkeit einer Glühkerze, als auch eine direkte Einspritzung in den Hauptbrennraum des Gasottomotors. Wegen der guten Zündfähigkeit ist der Anspruch auf gute Zerstäubung nicht so hoch wie bei der Dieseleinspritzung, sodaß einfachere Einspritzsysteme mit niedrigerem Druckniveau verwendet werden können. Weiterhin sind aus demselben Grund die einzuspritzenden Mengen für eine sichere Zündung des Gas-Luftgemisches tendenziell geringer als bei Dieselkraftstoff.The core of the invention is therefore the use of dimethyl ether (DME) as the ignition fluid for the ignition of gasoline engines. A version with injection into a prechamber can be selected here, but here without the need a glow plug, as well as a direct injection into the main combustion chamber of the gasoline engine. Because of the good ignitability, the requirement for good atomization is not as high as for diesel injection, so that simpler injection systems with a lower pressure level can be used. Furthermore, for the same reason, the quantities to be injected for a safe ignition of the gas-air mixture tend to be lower than with diesel fuel.

Als Einspritzsysteme eignen sich beispielsweise: Pumpe-Leitungs-Düse-System mit Recheneinspritzpumpe (elektronisch gesteuert); Verteilereinspritzpumpensystem; Pumpe-Düseelemente oder eine Druckstoßeinspritzung.Suitable injection systems are, for example: pump-line-nozzle system with rake injection pump (electronically controlled); Distributor injection pump system; Pump-nozzle elements or a pressure surge injection.

Bisher ist nur bekannt, daß DME als alleiniger Treibstoff in Dieselmotoren verbrannt wird. Eine Verwendung von DME als Zündfluid war dabei nicht vorgesehen.So far it is only known that DME is burned as the sole fuel in diesel engines. It was not intended to use DME as the ignition fluid.

Die Erfindung wird anhand der nachstehenden Figuren näher erläutert.The invention is explained in more detail with reference to the figures below.

Fig. 1 zeigt ein erstes Ausführungsbeispiel eines Zylinders eines Gasottomotors mit Zündfluideinspritzung in den Hauptbrennraum. Fig. 2 zeigt ein zweites Ausführungsbeispiel mit Zündfluideinspritzung in eine Vorkammer.Fig. 1 shows a first embodiment of a cylinder of a gasoline engine with ignition fluid injection into the main combustion chamber. Fig. 2 shows a second embodiment with ignition fluid injection into a prechamber.

Zur Verwirklichung der Einspritzung von DME als Zündfluid in den Gasottomotor wird gemäß Fig. 1 DME mit einer Einspritzpumpe 1 bekannter Technologie aus dem Vorratstank 3 über eine Einspritzdüse 4 zum gewünschten Zündzeitpunkt vorzugsweise direkt in den Hauptbrennraum 5 des Gasottomotors eingespritzt. Der vorzugsweise zwischen 170 und 1000 bar eingespritzte DME verbrennt unter dem Einfluß der der Verdichtung im Zylinder 6 entsprechenden hohen Temperatur im Zylinder ohne weitere Zündhilfe und setzt dadurch das im Brennraum befindliche magere Gas-Luft-Gemisch in Brand. Die Einspritzmenge beträgt vorteilhaft 0,5% bis 5% des dem Motor zugeführten GesamtenergiegehaltesTo achieve the injection of DME as ignition fluid into the gasoline engine, DME is injected with an injection pump 1 of known technology from the storage tank 3 via an injection nozzle 4 at the desired ignition point, preferably directly into the main combustion chamber 5 of the gasoline engine according to FIG. 1. The preferably injected between 170 and 1000 bar DME burns under the influence of the high temperature corresponding to the compression in the cylinder 6 in the cylinder without further ignition aid and thereby sets the lean gas-air mixture in the combustion chamber on fire. The injection quantity is advantageously 0.5% to 5% of the total energy content supplied to the engine

Es ist in einer weiteren Ausführung (Fig. 2) jedoch auch möglich, den DME in eine Vorkammer 7 einzuspritzen, wobei die Vorkammer 7 keine Zündhilfe und keine zusätzliche Gaszufuhr von außerhalb des Hauptbrennraumes 5 benötigt. Letztere Lösung wird vor allem dann eingesetzt werden, wenn ein bestehender Motor auf den Betrieb mit DME als Zündfluid umgestellt werden soll.In a further embodiment (FIG. 2), however, it is also possible to inject the DME into a prechamber 7, the prechamber 7 not requiring any ignition aid and no additional gas supply from outside the main combustion chamber 5. The latter solution will be used above all if an existing engine is to be converted to use DME as the ignition fluid.
